I just did a side-by-side in an aero cloner. I didn't watch which had roots first but after 3 weeks they all did. The difference between the two is that the ones from the mother plant had roots all along the stem, the ones that were cut 3 weeks into 12/12 only have roots from the cut end, but...

Thanks OldMed!

Help. First time DWC, FF neuts, PPM+1100, Ph=6.5, 3 weeks flower. Some fan leaves started turning yellow a few days ago in an area that was exposed to more light from training. Now the yellow ones have wilted and almost the entire plant is drooping, looks like it needs water. Water level...

Why does the Ph go down? First-time DWC. Foxfarm nutes. Set Ph at 6.5 and EC was at 1100 ppm mixed per FF instructions. Two buckets each with a different strain, in one the Ph drops in, the other one it doesn't. How come? Both are growing well but I keep having to add Ph up to keep it...

You should need to run it to the dryer vent, just exhaust it out of your closet after going through your charcoal filter. Your fan will have to work hard to move air through the filter and all that ductwork to the vent if you do what you've planned.

So what is the biggest advantage of a vaporizer other than reducing health risks?

The accoustic cabinet will not do anything for airflow noise, just motor noise.

People use what are called striper the ecentuate the pattern you mow it in. I think they are just a small steel roller that bends the grass over giving that ball park look.

Black out fabric has a white side and an off-white side. There is a layer of black plastic in between them that actually block the light.

You link is dead. You should go to a fabric store and ask for some "blackout" fabric. It is used in drapes to blackout light. Tell them you are building a darkroom for photography. Hang it behind the door and you will be pleased.

If you have about 5 times as much money to spend on lights as it will take with MH, HPS, or fluorescent LED's will work fine.

Okay no picture yet, I ‘ve got camera / computer problems but I could still use some help. I am about 10 weeks vegging in soil. Have been having problems with leaves hear and there getting brownw spots and then turning yellow and falling off. I thought it was nutrient burn at first. I was...

Fmj, Do you have any light leaks out of the cabinets? I wondered how well those doors block the light and if you have any that comes out your vents?

what kind of sockets do you have?

I don't think it is illegal to grow tobacco in the US

Capacitors are used to increase the "power factor" of inductive devices. Your light will not use 350 watts without it, but it will draw as much current as a say a 350 watt incandescent lamp, just not the wattage. If you are having trouble with overloading the circuit you might want to add the...

I put 6 2-0gallon grow bags in one of those underbed storage boxes. The box catches the run off and makes it easy to handle six plants. With grow bags you use you space more efficiently I think.

If you have mylar or another good reflective coating on the walls it will not make much difference how high the light is. I would put it up top and leave it there.

Hey FF, got any pictures of that 4 lamp fixture with 4 bulb sockets added? I don't think I know how to do that. Thanks.

There are standard and high output T-5's. The T-5 HO's put out about twice as much light as a standard T-5. The high output or HO's for short is fairly common to fluorescent lamps. There are T-12 HO lamps that have been around for a long time that would work well for growing. T-5 lamps are...
